  • Nephrite - A Homeworld ship pilot, mentioned by Bismuth to Pearl.

Additionally, Bismuth mentions "other Crystal Gems" who appear to be her close friends – "Biggs", "Snowflake", and "Crazy Lace". While unknown at the time, these were later confirmed to be Biggs Jasper, Snowflake Obsidian, and Crazy Lace Agate.


Many Corrupted Gems are seen trapped in cages in the Beta Kindergarten. Their bodies are hidden by shadows and only their glowing yellow eyes can be seen.


Another Corrupted Gem can be seen in a cage. Only her two eyes and large six-clawed hand can be seen.

Season 4

"Adventures in Light Distortion"

When Steven is adjusting the Roaming Eye's form calibration system for the Crystal Gems, a small type of Gem, possibly a Pebble, Aquamarine or gems of the Earth and Heaven Beetle type, can briefly be seen on the panel, which subsequently alters the Crystal Gems' forms to be small.

Also, a large type of Gem, presumably a Quartz, Topaz, Bismuth, Obsidian, or Tourmaline can be seen.

Season 5

"The Trial"

The defending Zircon states that Pink Diamond's entourage did not contain any Rose Quartzes and was instead composed of several Agates and Sapphires.

"Off Colors"

Various pieces of old statues can be seen at the beginning of the episode. One appears to be a fusion of two unknown Gems, with a large head of an unknown gem statue can be seen in the distance behind it. Another head of a large statue has a gemstone with the same cut as a Rose Quartz's on its forehead.

Rhodonite's components are an unknown Ruby and Pearl, while Fluorite's components are six unknown Gems.

The Rutile Twins mention in that the moment they emerged, the other Rutiles who saw them ran away in fear because of how they looked.

Morganite, an unknown Gem, is mentioned by Rhodonite. She owned the two halves of Rhodonite before replacing them after they fled. Morganite was supposed to appear in a Steven Universe Future episode, where it would be revealed that Rhodonite's Ruby and Pearl had fallen in love and fused many times before, with Morganite rejuvenating them each time. After getting discovered for the 18th time, the Pearl and Ruby ran away/were exiled by Morganite and joined the Off Colors as Rhodonite. The story ended up shelved for being much too complex for a single episode. It is revealed in Steven Universe: End of an Era that the episode would've also revealed her role in Homeworld society, that being a designer for the Diamond Palanquins.


During Garnet's brief flashback of the Rebellion, two unknown Gem silhouettes appear fighting Pink Diamond alongside Garnet, Pearl and Bismuth.

  • On the left of the image there is a Gem with short hair around the same height of Pearl. She appears to have a thin build. Her hair is similar to the Rutile Twins' or the prosecuting Zircon's.
  • On the right of the image there is a short Gem. She resembles one of the unknown Gems in "The Answer".

"Lars of the Stars"

A group of sixty-seven elite Citrines is mentioned by Emerald to have guarded her fastest ship, the Sun Incinerator, on the docking bay of the planet Klavius 7. Lars and the Off Colors are able to successfully sneak past all of the guards in order to steal the ship. Emerald also mentions that one of the crimes Lars and the Off Colors are accused of is impersonating imperial officers in a cosmic jubilee. While pursuing the Off Colors in her Destiny Destroyer, Emerald commands her crew, who remain offscreen, to fire on the Sun Incinerator's nova thrusters.

"Jungle Moon"

In Stevonnie's dream, the name shown on Dr. Maheswaran (who represents Yellow Diamond in the dream)'s phone is Nephrite-XJ Cut-763. She seems to have been reluctant to begin colonizing the planet due to the presence of organic life, causing Yellow Diamond to demand her to do her job, threatening to shatter her and her crew herself otherwise. According to the silhouette on the phone, she has spiky hair.

Yellow Diamond also attempts to contact the leader of the fleet, however, Pink Diamond interrupts her, so the leader's name and appearance are never shown.

"Your Mother and Mine"

Unknown Crystal Gems also appeared in the flashback, standing alongside Rose and fighting unknown Homeworld Gems at the Ancient Sky Arena.

Near the end of the episode, Rhodonite said there will be Agates on one of Yellow Diamond's Asteroid Mines that they were heading towards.

"A Single Pale Rose"

While Steven is in Pearl's gemstone, he presumably discovered her memories of the abandoned Gem Battlefield the second Pearl sent him to. There when he fell, he saw gemstones of inactive Gems in the sand. Later in the scene when Steven comes back from Pearl's gemstone, there are many Gems that witnessed Pink Diamond's shattering. In a following scene, there is a flail-wielding white Gem that Garnet poofs, and a Gem with a sword that Pearl fights.


"The Question"

Ruby mentioned being surrounded by other Rubies before meeting Sapphire.

"Made of Honor"

After Bismuth is unbubbled in the Burning Room, she reveals the names of several bubbled (and presumably corrupted) former Crystal Gems that she recognized, including Larimar.

  • "Tiger's Eye" - A corrupted Crystal Gem mentioned by Bismuth, formerly bubbled in the Burning Room, and presumably uncorrupted as of "Change Your Mind ".
  • "Beryl" - A corrupted Crystal Gem mentioned by Bismuth, formerly bubbled in the Burning Room, and presumably uncorrupted as of "Change Your Mind".
  • "Serpentine" - A corrupted Crystal Gem mentioned by Bismuth, formerly bubbled in the Burning Room, and presumably uncorrupted as of "Change Your Mind".

"Legs From Here to Homeworld"

Upon the arrival of Pink Diamond's ship, many Gems are seen cheering for the Diamonds. Among the Gems seen in the close-up of the crowd are a group of tall green Gems (possibly Era-1 Peridots or a related type of Gem) a group of short pink Gems, a group of pale blue Gems, and a group of flying Aquamarines.

Yellow Diamond is mentioned to be checking up on Citrine production reports.

Blue Diamond mentions that Pink Diamond used to call a batch of Pyrite "Fool's Gold".

There are several polygonal yellow Sentient Walls, which appear to be powered by an unidentified yellow type of Gem that possesses rhomboidal gemstones. They make up the wall in the hallway leading to Yellow Diamond's Extraction Chamber. These gems have a golden yellow complexion, flattened slab-like arms, and a large, human-like face underneath in a thin, window-like pane of tinted "glass". They all have a rhombus-shaped yellow gemstone on their "foreheads". The opposite side of the hallway appears to contain no imprisoned Gems, as the gemstone slot is empty and the walls lack faces or arms. In "Homeworld Bound", one of these Gems appears to be moving around an in-wall form, the reason for this is unknown as "Familiar" implies that the walls are objects with Gems trapped inside. It is also possible that these gems are of a specific gem type made exclusively for this purpose, and require to be attached to these walls in order to function.

There are also several statues making up a part of the entryway to Blue Diamond's pool chamber. One statue appears to have the capability to blink, confirming the gemstone embedded in the statue's forehead to be that of a living Gem.

"Together Alone"

Various types of Garnets — Demantoids, Hessonites, and Pyropes — are mentioned by Blue Diamond when she taunts Garnet.

There are two green statue-like structures, appearing to be Gems imprisoned in objects, each with a disco ball inside of their cage-like bodies and two large outstretched hands. The gemstones powering these devices cannot be seen.

Next to these statues, other, possibly gem powered, statues are seen playing what appear to be some sort of trumpet. Their Gems are on their foreheads, and they are also green. 

"Change Your Mind"

In Steven's dream flashback, Blue Diamond mentions a Kyanite colony. The silhouettes of unknown Gems can be seen surrounding and staring at Steven during his dream. Inside Yellow Diamond's bubble chamber, there are a number of unknown bubbled cluster gems. There are also yellow Sentient Bridges (presumably Gem-powered objects) seen leading to Yellow Diamond's bubble chamber and on the bridge Yellow and Blue Diamond land on during their fight.

An unknown brown haired gem appears when the corrupted gems are healed, likely being a Quartz due to having thick and messy hair.

Steven Universe: The Movie

During the broadcast of Steven's message, many unidentified Gems are gathered in a crowd at the Diamond Palace. On an unknown planet, several unidentified Gems can be seen viewing the message on a beach including two gems resembling the Heaven and Earth Beetles and a Peridot.

On another unknown planet dominated by a large city, a group of Gems is watching from a balcony. This group includes two Zircons, a Holly Blue Agate, a presumed Lapis Lazuli, two Topazes, multiple Quartzes, a Ruby, a Pearl, and two Peridots.

Their Gem types and gemstone locations are unknown, but their body types are similar to the Gem under them.

Cover C for the third issue of the original Steven Universe comics features Steven, Connie and Onion riding a roller coaster with a ride based on a Fusion in the background; the forehead gemstone, ballerina outfit and orange hair make it clear Pearl is one of the components, though who the other is and the identity of the Fusion herself is unknown.

On the fifth issue of the 2017 version, Garnet carrying an unknown bubbled gem.


  • The unknown Quartz warrior in "Sworn to the Sword" is voiced by Michaela Dietz, implying she may be an Amethyst.
  • The mineral classification of the now uncorrupted Crystal Gems are as follows (as mentioned by Bismuth):
    • "Tiger's Eye" is a variety of quartz.
    • "Beryl" is a rock type that includes gems like aquamarine, emerald, morganite, and bixbite.
    • "Serpentine" refers to different gems that come from the rock Serpentinite.
  • Pink Diamond calling the Pyrites "Fool's Gold" is a tie to the nickname given to that rock in real life.
  • During the Reddit Q and A , Rebecca Sugar explains the personality of a Lepidolite if it were ever to appear in the series.
  • In "Together Alone", gems of various colors with a nearly-cylindrical head shape are seen among the crowd at the ball. It's possible that these designs may be a reference or inspiration point from the video game series Katamari.
